Overview of Multi-Terabyte Support in Solaris Volume Manager

Starting with the Solaris 9 4/03 release, Solaris Volume Manager supports storage devices and logical volumes greater than 1 terabyte (Tbyte) on systems running a 64-bit kernel.


Note - Use isainfo -v to determine if your system is running a 64-bit kernel. If the string “64-bit” appears, you are running a 64-bit kernel.


Solaris Volume Manager allows you to do the following:

Support for large volumes is automatic. If a device greater than 1 Tbyte is created, Solaris Volume Manager configures it appropriately and without user intervention.

Large Volume Support Limitations

Solaris Volume Manager only supports large volumes (greater than 1 Tbyte) on the Solaris 9 4/03 or later release when running a 64-bit kernel. Running a system with large volumes under 32-bit kernel on previous Solaris 9 releases will affect Solaris Volume Manager functionality. Specifically, note the following:


Caution

Caution - Do not create large volumes if you expect to run the Solaris software with a 32-bit kernel or if you expect to use a version of the Solaris OS prior to the Solaris 9 4/03 release.


Using Large Volumes

All Solaris Volume Manager commands work with large volumes. No syntax differences or special tasks are required to take advantage of large volume support. Thus, system administrators who are familiar with Solaris Volume Manager can immediately work with Solaris Volume Manager large volumes.


Tip - If you create large volumes, then later determine that you need to use Solaris Volume Manager under previous releases of Solaris or that you need to run under the 32-bit Solaris 9 4/03 or later kernel, you will need to remove the large volumes. Use the metaclear command under the 64-bit kernel to remove the large volumes from your Solaris Volume Manager configuration before rebooting under previous Solaris release or under a 32-bit kernel.
